my primary commuter is set up as a 1x9, have also toured with this bike - lots of hills here. overtime i've carefully observed which ratios i use the most. those ratios are, around 37 gear in and 65 gear in, plus a middle step of around 49. this gear range is almost identical to that of a three speed IGH.
